This things is clearly not designed for residential roofs. For one thing, it's hideous. But mostly it's intended to be installed on the ridge of a standard commercial flat roof, tar-paper style, and take advantage of the effect which large walls have on the wind. Houses, being lower, having (generally) pitched roofs, and therefore no structural ridge, are not the intended market.
